Recovering setup after storage

[chrismilleruk (Chris Miller)]

Hi all,

I had my onefinity (original x-35) working well and I was getting to be quite proficient at it but then we packed it away and moved to a different country 2 yrs ago. I’ve only just found the bolts and base screws (they were in a safe place) and this week I’ve brought her back to life. Almost.

Looking for some easy answers to get me across the line.

1. The dual-rails aren’t quite moving in sync. I thought they were earlier so maybe I knocked something. (See video)

• Y1 seems to go in the wrong direction and the correct itself.
• I checked the reverse setting for M1/2.
• Any suggestions welcome.

Onefinity dual rails issue

2. what’s the best firmware now, I’m on 1.0.9. I saw a few forums posts but tbh it sounds like they gotin a pickle with the numbers so I’m asking the community.

3. the two dual rails were slightly twisted on unpacking. Not much, but enough that they didn’t sit flat with ~2mm play. I’m guessing this is related to the tension in the ball screw so I used the 2x top and 2x bottom bolts to reset it. I’m guessing that’s fine.

4. any other pointers for a machine coming out of hibernation? Maintenance & tramming presumably but what else?

Thanks in advance.

Ps my setup is dual rails for X, gantry for Y

Hey Chris,

@chrismilleruk

2. what’s the best firmware now, I’m on 1.0.9. I saw a few forums posts but tbh it sounds like they gotin a pickle with the numbers so I’m asking the community.

1.0.9 is still used by many, one reason to go to 1.3.0 alpha 2 would be if you want the PwnCNC VFD (DELIXI CDI-EM61) to appear in the VFD listing on the TOOL page.

1.0.9 has no selection for the beefy Z-20 assembly but you can enter the values manually and it will work fine with the Z-20.

You have four wires that go to a stepper motor, that go to two coils (coil arrays in fact). If one of the wires is failing, it can have the effect that the motor runs into wrong direction. You have a cable or connector issue.

@OnefinityCNC

Note: Any time the axis moves in the opposite direction than what you direct it to, it’s 100% of the time a bad wire/connection. Sometimes, something as simple as disconnecting and reconnecting the wires connection solves it. Follow below for more help and examples.

Sometimes they have simply a bad connection due to wear or corrosion of the tin plating. In this case, a little amount of KONTAKT 60 and then KONTAKT 61 can help.

Thanks!

I had already taken those steps to remove the twist so it was reassuring to see it in the video.

As predicted, it was a pushed in pin causing the connection issue. Now working very smoothly.

Re: the firmware, I don’t have the Z-20 or VFD setup currently but on plan, and great to see pwncnc take on the spindle problem.

Good morning Chris,

nice to hear that everything is running fine now.
